Auto Leaf Springs

MB294519 Leaf Spring

Automotive leaf springs are also called blade springs.

One end of the leaf spring is articulated with the frame, which transmits various forces and moments and determines the runout trajectory of the wheel. At the same time, it also has a certain friction damping effect. It is not only an elastic element of the suspension, but also a guide to the suspension. Leaf springs are still widely used in various automobiles.

It consists of multiple steel plates of varying lengths and curvatures. After installation, the ends naturally bend upwards. When the impact of the road surface is transmitted to the wheels, the steel plate will deform, which acts as cushioning and damping vibration. When it is arranged vertically, it also plays the role of guiding and transmitting force. Most non-independent suspensions use leaf springs as elastic elements, eliminate guides and shock absorbers, and are structurally simple.
